I assume you're thinking AL foil. Which wire would you wrap, plug wire
or unit pickup lead, and should it be grounded?

Karl, how about a photo tach reading impulses directly off the PTO?
Small spot of reflective tape and mount the sensor and you should be OK.

Karl might even be able to use a bike computer for the job when
calibrated. I've read about people that have fitted them to disc/drums
and they worked fine but having the pick-up on the propshaft was too
fast. That was for car use and I would suspect a tractor and the PTO to
be somewhat slower so may be OK.
